USED PARKER BOILER HT1920

OVERVIEW
 
Parker Industrial Boiler Thermal Liquid Heater — Model HT1920, Sales Order 966013. High-temperature industrial thermal liquid heating system rated at 1,920,000 BTU/HR maximum input and 960,000 BTU/HR minimum input on natural gas. Safety valve and trim maximum pressure 125 PSI. Complete skid-mounted thermal fluid heating system with expansion tank, thermal fluid receiver/storage tank, circulation pumps, gas train, insulated piping, Square D electrical panel with main disconnect, and all associated system components. ETL Listed, conforms to UL Standard 508, Certified CAN/CSA C22.2 No. 14. Manufactured by Parker Boiler Co., Los Angeles, California — one of the largest and most successful manufacturers of packaged boilers in the USA.
Parker Thermal Liquid Heating systems use the forced circulation of a special heat transfer fluid (thermal oil) as the heating medium — delivering high-temperature process heat without the high pressures associated with steam or hot water systems. Thermal fluid pressure depends on circulating pressure, typically less than 50 PSI regardless of operating temperature. Ideal for chemical plants, plastic molding, cooking/food processing, distillation, pipe coating, laundries/dye houses, wood veneer manufacturing, particle board pressing, soil remediation, and any process requiring precise high-temperature heat transfer.
